Patented Dec. 14, 1937 UNITED STATES 3 Claims.

This invention relates to improvements in Wringer heads and is directed more particularly to a unitary wringer head including a housing including mechanism for driving a wringer.

The principal objects of the invention are directed to the provision of a wringer head which is simple in form and efficient in its operation.

A further object of the invention is the pro-. vision of a wringer head wherein a driving element or elements are shifted into and out of engagement with the driving element as by being reciprocated in one direction or the other by a swinging operating member, there being novel means for transforming the swinging motion of the operating member so that it reciprocate's the driven element.

Various novel features and advantages of the invention will be hereinafter more fully referred to in connection with the accompanying description of the present preferred form of the invention, reference being had to the drawing wherein:

Fig. 1 is a partial side elevational and sectional view showing a wringer head embodying the novel features of the invention;

Fig. 2 is a sectional plan view on the line 22 of Fig. 1;

Fig. 3 is a fragmentary planview of the casing of the wringer head to explain certain novel features of the invention; and

Fig. 4 is a side elevational view of the operating member constituting a part of the invention.

Referring now to the drawing in detail the invention will be more fully described.

The wringer head of the invention consists of a casing indicated generally by 2 which func tions as a support and which has intersecting horizontal and vertical bores 4 and 6.

A vertical part 8 of the casing in which the bore 6 is located is adapted for resting on a column of a washing machine and it may be rotatable with respect thereto. Ill represents a drive shaft such as is usually associated with a wash ing machine and on its upper end there is a driving element in the form of a pinion l2.

Upper and lower ears I4 are provided which The gears 18 and collar 26 in Fig. l are shown in a neutral inoperative position and are shift able longitudinally along the bore so that either one of the gears 18 may be engaged with he pinion 12. According to the direction of re a: tion of the pinion 5. the shaft 28 rotatedin one direction or the other accordingly as one or the other of the pinions is brought into meshwith h ar The gears H! are preferably of the type known 10 as face-gears which have teeth extending in; wardly on their adjacent faces, Ari operating member 28 has a leg art 30 which is pivoted as by a screw 32 to the rear end 34 of the hous ng and forth from the neutral'inoperative po n shown in Fig. 1 to an operative position at eit side thereof. A shroud part 26 of theoperatifig mber 28 overl es the upper side ofthe housing.-

so that it may swing on a horizontal' axis baclg and a curving manually engageable part 38 ex} 20 tends forwardly and upwardly from the part ll; This member 28} is arranged to have operiiiig' ao therethrough so that an operator nia i'gras'p the part 38 to swing the operating member on pivot. I

A rib or ribs such 21542 on the outsideof the housing at the inner or right hand 'end ther f is arranged so that the forwardend of -theo ating member rests and slides thereon. To coverup this rib there are on either side of the. oper-i- 3O atingrnember .downwardly dependingeskirt portions '42. The forward end of the operating member 28 bears on the rib so that it may slide thereon as it is swung between operative and inoperative positions.

A slot 50 is provided in the upper side of the housing which is disposed beneath the operating member as shown in Figs. 2 and 3. This slot provides a cam surface or surfaces for a pin 52 carried by member 26 which extends through 40 the slot 50. As the pin 52 is moved along the slot in one direction or the other the collar or shifting member 26 and the gears l8 are shifted longitudinally.

A member 54 is pivoted at 56 to the operating 45 member 28 and a detent 58 associated therewith extends through an opening 60 in the said member. This is arranged to enter a socket 62 in the upper side of the casing. When the lever member 28 is in the neutral position shown in 50 Fig. 1, the detent is received in the socket 62.

To release the operating member for its swinging movements to shift the gears the part 38 of the operating member and lever 54 are squeezed between the fingers so that the detent 55 CID " 'of, it is not, desired to be limited thereto since is withdrawn from its socket. A spring 64 secured at one end to the member 28 bears on the lever 54 and tends to urge the member downwardly so the detent will pass into the socket when the operating member is moved from an operating position to its inoperative neutral position.

The underside of the shroud 36 of the operating member is provided with a slot 66 which preferably extends in a direction opposite to that of the slot 50 of the housing (see Figs. 2 and 3). At either end of the slot 66 there are sockets 68 having angularly disposed sides.

.As shown in Fig. 2, the operating member 38 is in a neutral inoperative position, the pin 52 being in the center of the slot 50. To shift pin 52 to bring one of the gears into engagement with the pinion, the pin 52 is moved along slot- 50. This'is accomplished by swinging the operating member in one direction or the other.

For instance, in Fig. 3 the parts forming the slot 56 and socket 68 of the operating member are shifted so as to move the pin 52 in such a direction as to move the gears l8 in Fig. 1 to the left. When the operating member has been tilted sufficiently to move the pin 52 so that the right hand gear is in mesh with the pinion, the said pin is in the socket of the operating member at the end of the slot 66.

The form of the socket will be clear from Fig. 3 and is'such that the pin is releasably held against accidental movements alongthe slot because it is received in a socket of the operating member. When however it is desired to return the mechanism to an inoperative neutral position, the operating member is swung toward the center or upwardly in Fig. 3 thereupon the side 61 of the slot brings up against the pin 52 to force it along slot 50 and through the slot 68. When the operating member has reached its inoperative neutral position, the pin in the position shown in Fig. 2 with reference to the slot and the detent enters the socket 62.
